Abstract To explore the relationship between the ejection velocity of unidirectional double-face rockburst fragments and the bedding dip angle()，seven groups of unidirectional double-face unloading rockburst experiments of sandstone with different were carried out by using a self-developed true triaxial rockburst experimental system，and the ejection velocity of double-face unloading rockburst in sandstone with differentwas analyzed by particle image velocimetry(PIV). The results show that the rockburst phenomenon and duration of the two free surfaces are not all the same，and that the average velocity change process of the two free surfaces can be divided into four stages：particle ejection or fragment stripping，fragment block breaking，fragment ejection and late ejection. In the process of double-face unloading rockburst，both the average maximum velocity and the maximum initial velocity of the two free surfaces change with in a concave parabola form，reaching the minimum and maximum values at 60° and 0° of respectively. The change processes of the peak stress and the maximum principal stress decreasing rate at the time of rockburst withalso show an upward concave parabola. In terms of the difficulty degree of rockburst，when is 60°，the rockburst is easy to happen but the corresponding rockburst intensity is the weakest. The horizontal bedding is the least prone to rockburst，while the rockburst is strong once it occurs. The difference of the rockburst intensity of sandstone with differentis affected by the brittleness and the peak stress of rockburst.

Key words： rock mechanics rockburst experiment double-face unloading bedding dip angle brittleness characteristic fragment ejection velocity
